Start with the easy stuff first, have you checked the CVT fluid level?

 

Hi, yes I have checked the CVT fluid level and it looks good

 

Lucas, keep in mind that there are no gears - just changing drive ratios.

How many miles on that Murano? There have been some reports here of improved behavior from high-mileage CVTs even if the oil test didn't call for it.

 

Hi guys, ok it seems as though the belts on the cvt gearbox actually slip when it gets very hot or driving the car for a long period.

We drove back home after our holiday and after about 7/8 hrs highway driving, when climbing hills or overtaking other vehicles with the cruise control on and without is when i noticed the belts slipping as the car would change a gear and the belts slip at 3000rpm's and wont stop unless throttle is released and kept at a steady position making it very difficult to overtake other vehicles, it feels like "belt grip, slip, grip, then slip slip slip" then have to take my foot off the accelerator and gently give it some throttle just to maintain the speed.

but when the car has been standing for about an hour then its back to normal until the cvt gets hot again?

The Murano has 146000kms on it

 

LucasM, have someone check codes, next thing, check CVT fluid level and when did you if ever change CVT fluid? May or may not need changing but the dealer can check the PPM deterioration test.

 

What is your location? Your IP comes back as US but not sure. Your CVT maybe still under warranty if less than 10 years from in-service date.

 

Bob1 - Thanks for the advice and i will have the car checked for error codes, i have not yet done a cvt oil change as i only bought the car about 5 months ago.

Zebelkhan - my location is South Africa, the vehicle is a 2007/2008 model

 

Lucas, we have many threads explaining some CVT may last almost forever. They have a test to check for deterioration. They measure the level and tell you if it is good or not.
It is not like normal tranny's where you change at 30K miles. Not even close to anything like that.

 

Ok thanks Bob1, im sure it might need a change of tranny fluid as the issues with the belt slip only occur when driving highways and the cvt is very hot, but if the car is parked for about an hour to cool down then there are no issues, when we drove back home from our holiday which was about a 14hr highway drive, it started to slip about 7-10hrs into the drive, stopped to put more fuel in and then got back on the highway and it ran fine until the cvt got hot again, but i will have the oil checked and changed if needed.

 

I was just wondering, could it also be a "clutch slip" on the cvt transmission?

 

Also does anyone know what color the CVT fluid is supposed to be? the dipstick displays a Red ATF fluid, is that the right color of the NS-2 fluid?

 

It should be a fairly clear fluid on the dipstick....

 

Red!? Heck no it's not supposed to be anywhere close to red. Someone has contaminated your Cvt fluid.

Take trans pan off I did on one and the push belt was in a million pieces in pan

 

I literally went threw everything I was told it could be until checking inside trans and there laid the problem
